ZJHS pneumatic high-pressure angle valve

ZJHS-220、ZJHS-320 pneumatic high- pressure angle valve used for high pressure, high pressure difference, severe cavitation, erosion conditions. Use multi-level throttle type to share pressure difference, reduce cavitation, erosion and stream damage torsion, improved using life of adjusting valve. Valve body is rectangular shape, valve spool is single-guide structure, simple flow path, small resistance, especially suitable for regulating high viscosity, containing suspended solids and granular media, prevent coke, bonding, blocking
